CONTROL APPARATUS OF HYBRID VEHICLE

摘要

A control apparatus of a hybrid vehicle has an abnormal sound generation condition determination unit that determines whether or not an abnormal sound generation condition of a gear train is satisfied, and a pressing processor that applies a pressing torque from a first rotary electric machine to the gear train when a retention time, which is a period in which the abnormal sound generation condition continues to be satisfied, exceeds a predetermined value, and that does not apply the pressing torque when the abnormal sound generation condition is not satisfied and when the retention time is within the predetermined value. A pressing torque setting unit sets a pressing torque to be applied by the first rotary electric machine to a direction to suppress an engine cam torque which may rotate an engine output shaft.

1. A control apparatus of a hybrid vehicle in which an engine, a first rotary electric machine, and a second rotary electric machine are connected to each other through a transmission mechanism including a gear train, the control apparatus configured to:
determine whether or not a drive state of the hybrid vehicle satisfies an abnormal sound generation condition of the gear train; and execute a pressing process to apply a pressing torque for reducing rattling from the first rotary electric machine to the gear train of the transmission mechanism when a predetermined condition is satisfied, and to not apply the pressing torque when the predetermined condition is not satisfied, wherein the predetermined condition includes the abnormal sound generation condition and a condition that a retention time, which is a period in which the abnormal sound generation condition continues to be satisfied, exceeds a predetermined value.
